PSI-MOS-RS422/FO 1300 E Serial to Fiber Converter
Connect RS422 and RS485 devices to fiber optic cable
- Extend serial data up to 28 miles
- Immune to EMI, RFI and transient surges
- Point-to-point or star configuration
- SC type fiber connectors
- Terminal Block for 4-wire RS422/RS485 Connections
The PSI-MOS-RS422/FO 1300 E Serial to Fiber Converter transparently connects 4-wire RS422/RS485 and INTERBUS devices to fiber optic cable. By transmitting serial data over optical fiber, these serial media converters provide an economical path to extend the reach of RS422 and RS485 devices.
Long Distance Serial Data Transmission over Fiber
Using the FO 1300 E Serial to Fiber Converter you can extend your serial data transmission up to 27km (16.7 miles) over multimode fiber or 45km (28 miles) over single mode fiber. The result is that any two pieces of asynchronous serial equipment, located miles apart, can communicate at full duplex over fiber optic cable at rates up to 2 Mbps.
EMI, RFI and Transient Surge Immunity
Another advantage of the FO 1300 E fiber optic transmission system is the electrically isolated connection of devices. Electromagnetic interference (EMI) is a common phenomenon in typical environments like industrial plants, warehouses and factory floors. This interference can cause corruption of data over RS422 or copper-based Ethernet links. Data transmitted over fiber optic cable however is completely immune to this type of noise, thus preventing the negative effects of voltage equalization currents and electromagnetic interference on the data cables. A Serial to Fiber Media Converter therefore enables you to inter-connect your serial devices over fiber ensuring optimal data transmission, increased availability of the system, and improved network design flexibility for point-to-point connections and star structures.
Flexible Fiber Optic Connections
The FO 1300 E operates at 1300 nm wavelength, using a separate LED emitter and photo-detector on SC type connectors. Almost any multimode or single mode glass fiber size can be used.
Power Budget Considerations
Calculating the power budget is critically important with planning the fiber optic link. The optical power budget is the amount of light required to transmit data successfully over distance through a fiber-optic connection. The amount of light energy available within the setup will dictate the length of the fiber optic cable run between serial media converters within the network. Optical power budgets are critical to help businesses avoid signal distortion. To learn how to calculate optical power budget read our technical note. Transmit and receive dBm can be found in the Hardware specifications.
Transmit each serial signal out over 10 fiber optic lines
Up to ten (10) Serial to Fiber Converters can be grouped together using the TBUS DIN Rail bus system for voltage and data. This allows the serial converter to operate as a star coupler, taking the serial data input signal and distributing it to all Fiber optic output ports.
High Quality Features and Support
The FO 1300 E are also equipped with comprehensive diagnostic functions to increase system availability, simplify start-up and permanently monitor the optical transmission quality. The integrated optical diagnostics allow permanent monitoring of the FO paths during installation and operation. The floating switch contact is activated when the signal level on the fiber optic paths reaches a critical level. This early alarm generation enables critical system states to be detected before they result in failure. These cost and time saving features, along with free worldwide technical support, make the FO 1300 E serial to fiber converter the smart choice for IT professionals.

PSI-MOS-RS422/FO 1300 E Serial to Fiber Media Converter Applications
- near heavy electrical equipment
- in environments with electrical (EMI) or radio (RFI) interference
- in environments with transient surges
- in industrial plants, warehouses and factory floors
- enabling asynchronous serial equipment to communicate at full duplex, with rates up to 2 Mbps, over optical fiber
Point-to-point connections between serial devices over fiber
You can use two PSI-MOS-RS422/FO 1300 E Serial to Fiber Converters to easily convert a data link from copper cable to fiber optics.
Star structures
You can network RS-422/RS485 4-wire devices within a star structure as a master/slave network. Depending on the number of star lines required, several PSI-MOS-RS422/FO 1300 E Serial to Fiber Converters are connected to TBUS DIN Rail bus systems for voltage and data. This makes up to 10 fiber optic ports available. Cross-wiring for serial data and for the supply voltage is provided automatically by the DIN rail connector.
INTERBUS Networks
PSI-MOS-RS422/FO 850 E converters also allow you to create INTERBUS networks with FO technology. For standard INTERBUS connections, the REMOTE IN and REMOTE OUT interfaces are converted to fiber optics using one PSI-MOS-RS422/FO 850 E terminal device each.
